-# Parser package
-
-## Installing
-
-Simply add `parser` to your config.php `always_loaded.packages` config option.
-
-## Included Parsers
-
-* Mustache - A lightweight, yet powerful templating library.
-* Markdown - A PHP version of Markdown by Michel Fortin.
-
-## Usage
-
-```php
-// old usage still valid, will load app/views/example.php
-View::forge('example');
-
-// load a SimpleTags template, will load and parse app/views/example.stags
-View::forge('example.stags');
-
-// load a Mustache template, will load and parse app/views/example.mustache
-View::forge('example.mustache');
-
-// load a Twig template, will load and parse app/views/example.twig
-View::forge('example.twig');
-
-// load a Jade template, will load and parse app/views/example.jade
-View::forge('example.jade');
-
-// load a Haml template, will load and parse app/views/example.haml
-View::forge('example.haml');
-
-// load a Smarty template, will load and parse app/views/example.smarty
-View::forge('example.smarty');
-
-// load a Dwoo template, ATTENTION: this one expects app/views/example.tpl
-View::forge('example.dwoo');
-```
-
-## Installing parsers
-
-Only Markdown and Mustache are included. While many other drivers are included, their libraries are not and are by default expected in `app/vendor/lib_name` (capitalize lib_name), you'll have to download them yourself. Don't change the casing or anything, keep it as much original as possible within the `vendor/lib_name` dir to keep updating easy (also because some come with their own autoloader).
-
-You can configure them to be loaded from other locations by copying the parser.php config file to your app and editing it.
-
-## Config and runtime config
-
-Currently the drivers still lack a lot of config options they should probably accept. They are currently all configured to work with one instance of their parser library, which is available to config:
-
-```php
-$view = View::forge('example.stags');
-$view->parser()->set_delimiters('{', '}');
-```

-PHP Markdown Extra
-==================
-
-Description
------------
-
-This is a PHP port of the original Markdown formatter written in Perl
-by John Gruber. This special "Extra" version of PHP Markdown features
-further enhancements to the syntax for making additional constructs
-such as tables and definition list.
-
-Markdown is a text-to-HTML filter; it translates an easy-to-read /
-easy-to-write structured text format into HTML. Markdown's text format
-is most similar to that of plain text email, and supports features such
-as headers, *emphasis*, code blocks, blockquotes, and links.
-
-Markdown's syntax is designed not as a generic markup language, but
-specifically to serve as a front-end to (X)HTML. You can use span-level
-HTML tags anywhere in a Markdown document, and you can use block level
-HTML tags (like <div> and <table> as well).
-
-For more information about Markdown's syntax, see:
-
-<http://daringfireball.net/projects/markdown/>
-
-
-Bugs
-----
-
-To file bug reports please send email to:
-
-<[email protected]>
-
-Please include with your report: (1) the example input; (2) the output you
-expected; (3) the output Markdown actually produced.
